Normal magic. Blessings. Healing. Regeneration. Celestial Shield. Guardian Angel. Song of Peace

and the creatures she has are not all necessary and useful...

There are useful ones - angels (resurrect)
Ballista and Archer do not have a penalty for shooting. + ballistas do not have a penalty for shooting through fortress walls
Pikeman - attacks from a distance of 2-3 cells, ignores the first hit
